Wireless transmission of electricity has been a dream of engineers for a long time. More than a hundred years ago, Nikola Tesla spent a fortune trying to build a device to transmit electricity over long distances. Today, in a world full of smartphones, laptops, and other devices that need frequent charging, that dream remains alive.
“Wireless” charging systems, like Qi, do exist, but they still require users to set a device on a charging mat, eliminating the need for cables but not the need to set your phone down. A company called Ossia hopes to change the industry with what it proclaims to be a true wireless charging system, and CEO Mario Obeidat stopped by Digital Trends’ CES 2018 booth to share some info about Ossia’s “Forever Battery,” a revolutionary take on an old design.
The Forever Battery comes in a AA form factor, and houses electronics (including an antenna) within its shell. Ossia’s Cota system uses a transmitter that beams electricity along direct paths through the air to the antenna in the battery, charging it from distances of up to 30 feet, with nary a wire to be seen between them.
“Think of Wi-Fi,” Obeidat said. “Just like you have a Wi-Fi router in the home, you have a Cota transmitter. You have many low-power devices, one of them could be the AA battery … inside of it has electronics that communicate and receive power from that transmitter.” The Cota system beams the power only through unoccupied space; if a person were to move in the way, Cota would angle the beam to avoid them.
Obeidat went on to explain that users could have the battery in a variety of devices, such as smoke detectors or remote controls, receiving power without hassle. He also emphasized that the AA form factor of the Forever Battery is just the start. Ossia believes it can scale the technology down to work in smartphone batteries. To this end, the company hopes to partner with large smartphone manufacturers to integrate Cota into their smartphone batteries.
Ossia’s tech is so radical that it has earned the CES Innovation Award for three straight years. Don’t expect Cota to replace power lines as the arteries of modern civilization, however. Cota is focused on low-power devices for now. “Once you’re talking about 10 watts and 20 watts, that becomes a little bit outside,” Obeidat said.
Still, if Ossia’s tech works, it would be a major convenience for consumers — and a great boon for the environment, given the hazards of battery disposal.
Samsung’s scandal over its Game Optimizing Service, or GOS, has returned with a bill attached. South Korea’s Fair Trade Commission has tentatively fined the company 20.1 billion won, or about $15.1 million, over gaming claims made for the Galaxy S21, Galaxy S22, and Tab S8.
The regulator says Samsung promoted the devices as gaming powerhouses without disclosing that GOS placed preset CPU and GPU limits on certain demanding games. Samsung disputes that conclusion, calling GOS a legitimate way to manage heat.
Apple's next cheaper iPhone could get a brand-new processor while keeping its most stubborn display compromise. Digital Chat Station tips the iPhone 18e for a 2027 release with a 2nm A20 chip and a 6.12-inch OLED screen still limited to 60Hz.
The rumored camera setup includes a single 48MP rear camera and a possible 24MP selfie camera. There's new hardware to consider, but buyers hoping Apple would extend that upgrade generosity to smoother scrolling could be disappointed.
Google Photos is introducing a new design for the Collections tab on Android, giving users more control over their albums, folders, and photo categories. The update is all about customization, allowing users to pin collections they access often, hide sections they use rarely, and rearrange the layout to make their photo libraries easier to navigate.
According to a 9To5Google report, the change comes after Google rolled out the redesigned floating navigation bar on Android earlier this year. Rather than inventing a brand new way to store photos, Google is making it easier to get to the content people want, without having to scroll through sections they rarely open.
